Sorry for re-posting the question, I did not get any reply. Kindly reply please if any one can. ### Hello R users,
I have a montly time series over a several year period. It's easy to compute a monthly climatology (12 values), Now, I would like to calculate the corresponding standard deviation, ie the 12 values calculated from the january values, february values, etc. What's the best way for such a calculation ?
